i understand analog circuit from this book.
there are many rules for you to remember to understand analog circuit, not just by calculation.
Just thought I'd let you know, you can get a lot of valuable, insightful analog design info from the various manufacturer's websites (maxim, TI, etc). This is a great way to help get practical knowledge of subjects after reading the theoretical stuff in books.
